In this thesis the feasibility of tailored follow-up for early-stage breast cancer patients is evaluated. In order to do so, we first determined the risk of locoregional recurrence (LRR) dependent on local treatment in a large cohort of low-risk breast cancer patients, treated with adequate modern systemic therapy. In the second part we evaluated both patients’ and professionals’ needs and preferences for breast cancer follow-up and we reviewed the literature on cost effectiveness of known follow-up schedules. Finally we prospectively examined whether the implementation of a tailored follow-up programme, based on a prognostic index for LRR, is feasible and acceptable to patients and professionals. The results show that in general, implementation of minimised tailored follow-up seems feasible, but professionals tend to more frequent follow-up. Patients accept less intensive follow-up schedules and follow-up by a nurse practitioner. Given the low risk of LRR, tailoring should not only be done based on this risk, but individually, based on the presence of treatment related side effects, either physical or psychosocial. If patients do not experience side effects, annual planned mammography and telephone contact coordinated by a single professional, preferably a specialised nurse, suffice in case of easily accessible information and on demand visits.
